An electroceramic response model for a SnO<sub>2</sub>-NiO composite solid oxide sensing material of&nbsp;<em>n</em>-type conductivity inside the porous material is coupled with a transient flow field simulation of the delivery of a formaldehyde pulse to the sensor surface. Coupled volumetric CFD domains are used to examine the effects of the transport of formaldehyde from a preconcentrator unit to the sensor, and its implications for interpreting the sensor signals from laboratory experiments.</div>}, number={2}, journal={The International Journal of Multiphysics}, author={Darcovich, K and Tunney, J and Dunford, J and Styles, L and Xiao, G and Constant, A}, year={2011}, month={Jun.}, pages={101-114} }
